azure cosmos changefeed estimator in java

Question

I'm trying to implement changefeed estimator in java. But having a hard time finding api for that. Wondering if anyone has a sample of it. Here is the link to the .net implementation of what I'm looking for https://docs.microsoft.com/bs-latn-ba/azure/cosmos-db/how-to-use-change-feed-estimator

Answer 1

There is the source code Azure/azure-cosmos-dotnet-v3/Microsoft.Azure.Cosmos.Samples/Usage/ChangeFeed/Program.cs of sample code of the offical docuemnt Use the change feed estimator .

And there is the sample code for ChangeFeedProcess in Java Azure/azure-cosmosdb-java/.../examples/ChangeFeed/SampleChangeFeedProcessor.java .

The difference is that there is not a function GetChangeFeedEstimatorBuilder of class Container in Azure Cosmos Java SDK, but it seems that the C# implementation for GetChangeFeedEstimatorBuilder also to generate a ChangeFeedProcess instance, so I think you can refer to the C# code to write your Java one.

Here is the related C# source code as references for you.
